| 摘 要： | 本文基于遥感和地理信息系统技术,利用Landsat系列遥感图像的解译成果以及有关信息,分析了北京1984-2002年城镇交流程度对北京城镇扩张的影响。研究表明:北京近18年来交流环境对北京各区县城镇扩展起到了一定的推动作用,且其作用优势逐渐抵补山区给城镇扩展带来的阻扰;此外,一个区(县)若与其周围各区(县),特别是与中心城市或离中心城市较近的区(县)有良好的交流环境,则它的城镇扩展机会也将越大。

| Abstract: | Based on the technology of RS and GIS, this research makes an analysis on the influence of exchanging intensity on the urban expansion in Beijing from 1984 to 2002, which makes use of the translation result formed by series of Landsat RS figures. A conclusion is drawn that the exchanging environment has had some positive effects on the built - up land expansion in Beijing in recent 18 years and with the process of urbanization the influence of exchanging has recovered the negative effect of mountain regions gradually. Besides, the opportunities of a countyg.expansion would get more if it has been in good exchanging econdition with the counties around, especially with the core regions or the counties close to the core regions. |
